Design and Implementation of AXI UPSIZER DOWNSIZER for GPU based Subsystem

Abstract

To increase the performance of ARM System on chip(SoC) subsystem, need to increase the data flow from system components to memory. This report focuses on how advanced micro controller bus architecture(AMBA) protocol can be expanded from 128bit to 256bit data width on the bus. To make this possible, one internal module is developed which takes care of all protocol specification and rules. The generated module is verified by number of tests which includes read and write trans- actions. The UVM test bench is developed for this particular unit level verification, for which protocol checkers are implemented and performance counter will measure successful number of transaction. After that performance parameters of the system will be evaluated and the module will be integrated in the subsystem to increase the data flow. This project can be extended to for protocol like ACE and CHI.
